This book compiles reliable protocols for preparation of intermediates for carbohydrate synthesis or other uses in the glycosciences. Protocols and methods are verified independently to ensure reproducibility. The text includes more detailed version of protocols published previously and published by others in the past or in not readily available journals. It also contains protocols developed in the authors' laboratories or elsewhere, even from a long time ago. The essential characteristics of the protocols presented are reliability and the expectation of wide utility in the carbohydrate field.
